#1: Catalytic Converter?? Author: Davina, Posted: Fri Jul 04, 2014 9:01 am ---- Hi, I hope someone can help. I recently got a 2000 206 which had just had the part of the exhaust system before the cat professionally replaced. It passed the NCT (MOT) with flying colours so I thought it was a good car.
A couple of days after getting the car, I was driving on the motorway and it started losing power. I pulled off the motorway and the boyfriend had a look, only to find that the cat was red hot. We had no choice but to drive to the local autoparts shop where it was suggested that we order a new cat. We were also told that it would be a good idea to remove the cat that was on the car as it would make getting home easier. So we did this.
The new cat arrived and when the boyfriend went to fit it, he discovered that the section coming from the engine toward the cat was covered in gun gum (apparently this is very bad) but he cleaned it all out and welded in the new cat. We took the car out for a spin to get the cat up to temp as suggested, and the same thing happened again. The cat was red hot, there was power loss and the damn thing is noisy as hell.
So to get to the point, does anyone know what the deal is?? I have never had such problems with a car before. A friend has a diagnostic kit which revealed nothing wrong. It is beyond a joke at this stage.
Any help would be greatly appreciated.

#3: Re: Catalytic Converter?? Author: macca1411, Location: Westhoughton, LancashirePosted: Fri Jul 04, 2014 9:55 am ---- It's normal for a cat to run at temperatures upto 1600 degrees F (870C), and it only starts working correctly above around 500 degrees F (260C). Anything above 2000 F (1093C) is bad.
Any type of exhaust paste before the cat can ruin the cat, so your boyfriend was right to remove all of this. I can't understand why he had to weld a new cat on though as they are bolt on.
#4: Re: Catalytic Converter?? Author: Davina, Posted: Fri Jul 04, 2014 10:38 am ---- Vexs - I haven't noticed the car overheating at all.
Macca - The new cat had a larger diameter pipe heading toward the back box than the original did. He did contact the bloke in the auto parts place who has tons of experience with 206s who recommended welding it. Is it normal for the cat to actually become cherry red after a 5 mile round trip? A few sites have suggested that changing the plugs and/or the coil pack can remedy cat problems...would you agree?
Thanks a million for the replies!

#7: Re: Catalytic Converter?? Author: Edward, Location: In the garagePosted: Sat Jul 05, 2014 1:19 am ---- Sounds like unburnt fuel could be getting into the cat. Or there could be a few other logical reasons.

I used to get a glowing manifold on my 1979 Ford Pinto 2.0 engine, although that did have a few changes made to it to increase the output to around 120bhp.
OP, you could do with getting some live data readings.
I don't think we have established which power unit you're running yet. That information might be useful.
#9: Re: Catalytic Converter?? Author: Davina, Posted: Sat Jul 05, 2014 4:23 am ---- Steve206 - There are no warning lights coming on at all, which makes things more difficult to diagnose. To make matters worse, the boyfriend was in an accident yesterday and flipped his C180, ending up on the roof in a ditch so I really need to get this sorted.
#10: Re: Catalytic Converter?? Author: Davina, Posted: Sat Jul 05, 2014 4:24 am ---- Macca - How would I find out what which power unit is in the car?
Thanks again for the replies lads.
#11: Re: Catalytic Converter?? Author: Edward, Location: In the garagePosted: Sat Jul 05, 2014 4:32 am ---- The problem will be elsewhere, the glowing cat is just a symptom.

#13: Re: Catalytic Converter?? Author: Davina, Posted: Sun Jul 06, 2014 6:22 pm ---- Apologies for not getting back here sooner, I have sent the 206 off to a mechanic to have it done properly. Once I have a diagnosis and/or solution I'll post it here. Thanks again for all the input!
#14: Re: Catalytic Converter?? Author: Davina, Posted: Wed Jul 09, 2014 4:43 am ---- A new coil pack fixed the problem! Thanks for all the help lads!!
